Answer:
$124,400
Explanation:
The scholarship pays for 30% of her tuition. This leaves her responsible for 100-30 = 70% of it. 70% = 70/100 = 0.7; this makes her part of the yearly tuition
0.7(29500) = 20650
She is still responsible for her $9600 room and board per year. Her books are paid for by the scholarship; however she still has the lab and facility fees at $850 per year.
Altogether this gives her a total of
20650+9600+850 = 31100 per year. Over the course of 4 years, this will cost her
31100(4) = 124400
